@Shima try these tricks to restart your phone service. You could try in order:
1. Restarting your phone. Turn your phone off, wait 30 seconds and restart.
2.Putting your phone on aeroplane mode for 5 minutes. Take it off and restart.
3.From your self service account enable the lost/ stolen feature log out, wait 5 minutes, log in and take it off. Log out and restart your phone.
4. Add a one time payment and of $2 To your account and restart your phone .
If these tricks don't work contact a moderator and ask them to reset your SIM. Click on the green questionmark in the white circle at the bottom right of your screen. This connects to the autobot Simon. Type moderator and follow the prompts to get to one (CLICK on "Account specific question" and "No I want a human" and "Submit a ticket Click me!")
Once connected, you will be asked to log in again with your community user name and password. Please do, this allows you to continue and send your message.
Check your private message sent box (click on the envelope top right of your screen) to make sure the message was sent. Also keep an eye on the envelope, the mods answer will show up there. Once it does, you will be asked to verify your self service account, with your password and login. Doing allows the process to continue.
You can also enable email notification to receive a private message notification sent to your email. Go into your community account > my settings > PREFERENCES > Private Messenger > enable "Receive email notifications for new private messages" > Save
